BRUSH ESPECIALLY ADAPTED FOR CLEANING STOVEPIPES.

Application filed November 20, 1918.

To all whom it may concern:

Be it known that 1, JOHN JoKIsoH, a citizen of the United States,residing at Detroit, in the county of l/Vayne and State of Michigan,have invented new and useful Improvements in Brushes Especially Adaptedfor Cleaning Stovepipes, of which the following is a'specification.

This invention relates to an improved brush primarily devised forremoving the soot from stove pipes.

The object of the invention is to produce a brush of this kind whichshall be of a collapsible nature whereby the same may be readilyinserted in the sections of a stove pipe and thereafter brought tooperative position to contact with the interior of the pipe and removethe soot therefrom.

Figure 1 is an elevation of a collapsible brush constructed inaccordance with this invention, parts being in section.

Fig. 2 is a face view thereof.

The improved brush is broadly indicated by the numeral 13, the sameincluding a handle 14: which is constructed of any desired number ofsections each hingedly connected as at 15. One of the sections, adjacentthe hinge thereof has arranged thereon a slidable bolt 16. The adjacentsection is provided with a keeper 17. The hinges are so connected andthe bolt is so arranged that the handle sections may be folded againsteach other when not in alinement so that the brush 13, when not in usewill constitute only a comparatively small article which may be readilystored. The bolt and keepers are therefore arranged in suitabledepressions in the respective sections of the handle. To the outersection of the handle 14 is hingedly connected, as at 18 the innerstraight ends of two approximately semicylindrical plates 19. Theseplates have their rounded outer surfaces provided with bristles 20 whichform the brush proper, the plates providing the heads of the brushes.The plates upon their outer surfaces are formed with depressions 21, sothat when the same are folded together the end of the handle will bereceived in the said depressions and the faces of the plates may bebrought into contact with each other.

plates, upon their outer surfaces have secured thereto each a flexibleelement 22, the said elements passing through a suitable opening 23 inthe outer section of the handle and through one of a pair of lateralextensions 241' on the said handle. The flexible elements are broughttogether and are guided through suitable eyes 25 in the said outersection of the handle. It will be apparent that a pull upon theconnected flexible elements will cause the plates to be swung outwardlyof the handle upon their hinges and be brought together so that thebrush in this manner is folded to permit of the ready insertion thereofthrough the opening in the knee or elbow. The lateral extensions providea support for the plates 19 when the same are in their spread posi- Ition and the brush isin operative position. Secured to the outer sectionof the handle is an angularly arranged cutter member 26 7 that may bebrought to contact with the inner surface of the stove pipe 1 todislodge any crustation therefrom which can not be removed by the brush.

To hold the brush in its open position, I secure to the inner faces oftheplates 19 flexible elements 27. These elements are guided throughsuitable angle openings 28 in a plate or bar 29 secured to the outersection of the handle and also through an eye 30 on the said outersection of the hancent sections for retaining said sections inalinement, a brush comprising two semicylindrical plates having theirstraight edges hingedly connected to the outer section of the handle andtheir outer peripheries provided with bristles, means on said outerhandle section for supporting the brush plates when the latter are inalinenient, an angularly disposed cutter member on said outer section ofthe brush, flexible means connected with the plate, guide meanstherefor, one of said flexible means designed, when a pull is exertedthereon to swing and retain the brush sections in operative p0sition andthe other of said flexible elements designed when a pull is exertedthereon to swing said sections toward each other and 10 collapse thebrush.

In testimony whereof I afiix my signature.

JOHN JOKISCH.
